Cold Rad, Cold inlet pipe and noisy system

[dunsmure]

Hello
I have quite an old system, the kitchen radiator which is furthest from the boiler is permanently cold, even the pipes its connected to are cold - almost like no water is getting that far.

tried bleeding it but its air free.

Also, rad in the bathroom needs bled every hour or so but is hot otherwise

Please help if you can. Its too cold to make tea in the kitchen !

Thanks

Check water level in cistern or system pressure if sealed first.
Turn all rads off except problem one and see if hot water is pushed thru to it.
If so you need to balance system, do a search.
If no joy , bleed the pump.
Your bath rad is getting air to it somehow, suspect refilling from cistern (if you have one of course.
Let us know how you get on
